Installed homeduino plugin, set it up as gpio, transmit and receive, debug on, gpios 1 and 0. no success, meaning when I went to messages -> homeduino -> all (info, debug, error, …) I got no messages at all.

however, i had also pilight on my rpi, so I tested using pilight-send and pilight-receive: both worked fine. So I assume my hardware is not broken.

sudo make upload successfully did its thing without errors; I had forgotten to change the monitor port before and got connectivity problems, so I guess this time everything went the way it ways supposed to.

Still, no success.

What am I doing wrong? My hardware is obviously working fine, at least the receiver and transmitter are. My funduino ought to be fine as well (and even if it was not, connecting my 433 modules directly to my pi should have worked in that case).

I did wrongfully connect 5V when first connecting my 433 modules (rather than 3.3V as I should have). However, after I switched to 3.3V I could still send and receive via pilight-send and pilight-receive, so I assume no damage to the hardware has been done. Even if so, this should have only damaged my raspberry pi #17 and #18 pin and would not explain why the arduino clone is not working correctly.

I would greatly appreciate some help. By the way, all I am trying to do for now is to automatically trigger a self-written python script whenever pimatic (or my pi somehow) detects a certain signal (my 433MHz doorbell transmitter; I have already figured out it’s unique uuid, but could not successfully manage to constantly listen on my receiver for that signal).

Thanks in advance for your help and sorry if some stuff sounds wrong, not a native English speaker…

Hey @Ben-S.!
Do you have any debug data from the homeduino plugin?
If the mega has been flashed correctly then you should get an ack at least.
what could be is that the usb port at the plugin settings does not match.
better to use the serial-by-id or serial-by-path method?https://forum.pimatic.org/topic/42/tip-homeduino-usb

Actually, there is one more problem. Now I can receive signals, but is there a way to trigger them as well? I am trying to run a custom script whenever my receiver receives a signal; seems there is only an option to trigger sending a signal when something happens, but not set a trigger when receiving a signal…?
